:

Remove the rope rotor. 

The bits of spring might still be 
under tension and could fly apart 
when you take them out of the fan 
cover. To reduce risk of injury, wear 
eye and face protection and work 
gloves.

:

Use a screwdriver to carefully 
remove the parts of the spring.

:

Lubricate the new spring with a few 
drops of non-resinous oil.

:

Place the replacement spring with 
frame in the fan cover – the spring 
loop must engage the lug in the fan 
cover.

:

Apply a suitable tool (screwdriver, 
punch or similar) to the recesses 
(arrows) and push the spring into its 
seat in the fan cover – the spring 
slips out of the frame in this process.

:

Reinstall the rope rotor, tension the 
rewind spring, fit the fan cover and 
secure in position with the screws.

For periods of about 3 months or longer:

:

Drain and clean the fuel tank in a 
well ventilated area.

:

Dispose of remaining fuel and 
cleaning solution properly in 
accordance with local 
environmental requirements.

:

Run engine until carburetor is dry, 
this helps prevent the carburetor 
diaphragms sticking together.

:

Remove the saw chain and guide 
bar, clean them and spray with 
corrosion inhibiting oil.

:

Thoroughly clean the unit, 
pay special attention to the cylinder 
fins and air filter.

:

If you use a biological chain and bar 
lubricant, e.g. STIHL BioPlus, 
completely fill the chain oil tank.

:

Store the unit in a dry and high or 
locked location, out of the reach of 
children and other unauthorized 
persons.
